This article is my usual go-to and lists several reasons why JavaScript might not be available, and thus why you shouldn't take it for granted: https://piccalil.li/blog/a-handful-of-reasons-javascript-won...
- the user explicitly disabled JavaScript
- the browser does not support JavaScript (I sometimes view websites using elinks)
AFAIK screen readers also work better without JavaScript, so it's also an accessibility issue.
As I just said, users who explicitly disable JavaScript cannot even use Google Search. Why should I accommodate those users when even Google refuses to do so? They are actively choosing to have a limited web experience. The vast majority of the internet is completely broken for them.
I built and maintain a static site for a company, and it's just wonderful. It opens instantly (which the search engines like), rebuilding and deploying is trivial, I am not forced to update every week because the JS framework has a new vuln.(There are a few dynamic, JS-based parts that load dynamically and fail gracefully.)
If anything, hiding the hamburger menu behind an HTTP response is *less accessible*!
are you comparing fully client rendering vs SSR without client JS at all? are you building a marketing site or a dashboard type tool?
there is subtly to why each decision would be made based on these.
i think HN tends to demonize JS because we're all well aware of how bad the state of a lot of web apps have become with developers only knowing react and having no background in web fundamentals or accessibility.
i see no reason to completely shun JS, just use it intentionally and not reflexively.
I'm currently building a web-based tool that uses dynamic forms for UI, without the help of of a framework (yeah I know; I have reasons). This is the result: https://github.com/KaliedaRik/sc-filter-builder/blob/main/js...
It's not "easier" using Javascript; raw Javascript websites are a nightmare to build, maintain and reason about. It is "easier" with Javascript + current-favourite-framework-of-the-day.
Also: accessibility, SEO, the all-new Generative Engine Optimization (GEO) thing, etc.
